Yahoo Mail with 2 step verification does not work

Hello. I am running X-notifier on a Windows 8.1 machine and I have updated my security settings in Yahoo to include 2 step verification. However X-notifier no longer works for Yahoo. I have tried deleting all the cookies, I have tried generating a password from the Yahoo account (like I did for Mail on Windows 10). No matter what I did checking does not function... Do you know what else I can try?

 

 

I managed to fix it...don't know how, but after multiple reinstalls and relogins it works.

This is getting bad... the SPAM is starting to outnumber the real posts :(
